Riccardo, I'm afraid the best you'll ever get is something like this: x0 = 3; Table[{t, x0 = x/.FindRoot[Cot[x] + x == Cos[t], {x,x0}]}, {t,0,6.3,.1}] soln = Interpolation[%] Plot[soln[x], {x, 0, 2*Pi}] ----- Selwyn Hollis http://www.math.armstrong.edu/faculty/hollis On Friday, June 6, 2003, at 09:50 AM, Bartolini, R (Riccardo) wrote: > I have to solve the following transcendental equation > > > > Cot[x] + x = g(t) > > > > where g(t) is a function of t (e.g. Cos[t]) and I''d like > > to get x as a function of t.
